Dab tsi yog qhov txawv ntawm qhov hloov pauv hloov hluav taws xob thiab lub tshuab hloov pauv?
Lub transformer yog ib yam khoom siv uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov voltage, tam sim no, thiab impedance. Transformers feem ntau yog siv nyob rau hauv alternating circuits.
Hloov fais fab mov yog ib hom khoom siv hluav taws xob uas siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob los tswj lub sij hawm sib piv ntawm kev hloov cov transistors rau thiab tawm, thiab tswj cov zis hluav taws xob ruaj khov. Hloov fais fab mov tuaj yeem muab faib ua ob pawg: AC / DC thiab DC / DC; Raws li seb puas muaj hluav taws xob sib cais ntawm cov tswv yim thiab cov zis, nws tuaj yeem muab faib ua ob pawg: ib qho yog hu ua cais DC / DC converters; Lwm hom yog hu ua non-isolated DC / DC converters tsis muaj kev sib cais. Hloov cov khoom siv hluav taws xob muaj kev tiv thaiv xws li overcurrent, overheating, thiab luv Circuit Court. Qhov voltage input ntau yog dav, thiab qhov kev sib cais voltage ntawm cov tswv yim thiab cov zis yog siab.
LED zaub cov ntxaij vab tshaus feem ntau muaj xws li cov zaub modules, tswj systems, thiab fais fab mov systems. Cov zaub module yog tsim los ntawm dot matrix ntawm LED teeb, lub luag hauj lwm rau emitting lub teeb rau zaub; Lub kaw lus tswj tau tuaj yeem tso saib cov ntawv nyeem, duab, yeeb yaj kiab, thiab lwm yam ntsiab lus ntawm lub vijtsam los ntawm kev tswj qhov ci ntawm qhov chaw sib thooj. LED zaub screen txais lub tshuab hluav taws xob qis qis, thiab lub zog hluav taws xob yog lub luag haujlwm rau kev hloov cov khoom siv hluav taws xob thiab tam sim no rau hauv qhov hluav taws xob thiab tam sim no xav tau los ntawm lub vijtsam zaub. Lub tshuab hluav taws xob siv lub tshuab hluav taws xob hloov hluav taws xob, uas muaj cov yam ntxwv ntawm tus nqi qis, me me, lub teeb yuag, yooj yim peripheral circuit tsim, kev ua haujlwm siab, tsis tshua muaj suab nrov, ruaj khov thiab kev ntseeg tau.
Transformers nyob rau hauv kev hloov pauv cov khoom siv hluav taws xob feem ntau xav tau huab cua sib txawv kom nce lub zog khaws cia
Ua ntej ntawm tag nrho cov, los kho nws, lub transformer ntawm ib tug switching fais fab mov feem ntau yuav tsum tau tawm ntawm ib tug huab cua sib txawv, nyob ntawm seb hom switching fais fab mov nws yog:
Txij li thaum muaj ib qho kev hloov pauv, koj tuaj yeem tshawb nrhiav flyback circuit ntawm Baidu. Lub transformer sab hauv yuav tsum muaj qhov sib txawv ntawm huab cua los khaws lub zog. Hauv lwm lo lus, qhov sib txawv ntawm huab cua tsis nce lub zog kom khaws cia, tab sis ua kom lub zog cia ntim kom loj.
Koj tuaj yeem tshawb fawb ntawm Baidu rau pem hauv ntej circuits lossis tag nrho choj, ib nrab choj, thawb-rub circuits. Lawv cov transformers tsis tas yuav tsum muaj qhov sib txawv ntawm huab cua, uas cuam tshuam nrog kev ua haujlwm ntawm lawv cov circuits. Cov huab cua sib txawv tuaj yeem txo lawv cov kev ua haujlwm.
Thaum kawg, yog tias koj lo lus nug yog "Qhov inductance ntawm lub zog hloov hluav taws xob feem ntau yuav tsum muaj qhov sib txawv ntawm huab cua, puas yog ua kom lub zog khaws cia?", txawm tias koj nug nruj me ntsis. Kuv tuaj yeem qhia rau koj tias qhov sib txawv ntawm huab cua ntawm ib qho inductor dav dav zoo ib yam li cov transformer hauv flyback circuit tau hais ua ntej. Qhov sib txawv ntawm huab cua tsis ua kom lub zog khaws cia, tab sis ua kom qhov loj ntawm lub zog cia ntim.
